To all whom it may concern:

Be it known thatl', lV LLIAM -H H1 RY Pnnnm, of the town of NewLiskeard, in the district of Nipissing, in the Province of On: tarioCanada, have invented certain new and useful Improvements in Shockers,of which the following is the specification.

My invention relates to improvements in shockers, of that class whichgathers the sheaves into the form of a round shock and deposits theshock so formed in an upright position on the ground and the object ofthe present invention is to construct .a simple, light, cheap anddurable attachment for a harvester binder, which will either gather thesheaves into a complete shock and deposit the shock or will gather anddeposit any number of sheaves forming an incomplete shock when sodesired.

It will be noticed on referring ,to' Fig. 3, that the plate 21 isprovided with a depending central boss 21 throughwhich the axle 85extends, the upper face of the plate being provided with a recessedportion 38 for a purpose which will hereinafter appear.

39 indicates a normally stationary cupped tripping member provided witha central orifice 39 through which the axle 35 extends. The base of thecup fits between the boss 21 and the central port-ion or hub of therevoluble member 36. The upwardly extending flange portion of the cupfits against the lower face of the plate 21 and is provided with anannular outwardly extending flange portion i0 provided with ratchetteeth 11. The revoluble member 36 is supported in position upon the axleby a cross pin 12. 43 indicates my sheaf receiver. The sheaf receiver4.3 is formed by a plurality of canvas strips it, i5 and 46.

When constructing the receiver these strips are laid one upon the otherand stitched together by a line of stitching extending vertically downthe center of the strips. The outer strips 15 and 16 are turnedoutwardly at an angle each of the strips being provided with hems 17 inwhich are inserted reinforcing wires 48, see Fig. 5 holding the stripsin place to form the pockets a9, 50, 51, 52, 53 and 54. 55 indicates asleeve freely mounted upon the axle 35 and provided with an annularoutwardly extending flange 56 to which the inwardly extending upper endsof the wires 18 are suitably secured. 57 indi cates an inverted U-shapedbar secured at its lower end in the flange 56 and extending at its upperor looped end over a pair of spokes of the revoluble member 36 as indicated in Fig. 2 of the drawings. By this means the receiver 43 iscarried so as to revolve with the member 36. 58 indicates a collarloosely mounted upon the axle and provided with radial arms 58*. 59indicates lugs extending from the revoluble member 36 and arranged inpairs.

60 indicates an arm supporting member. The member 60 comprises a centralhub portion 61 having a central orifice 62. 63 indicates an armextending from the portion 61 provided with a laterally extending lug6&- having an orifice 6.4 and a downwardly ex tending lug 65 having anorifice 65 66 in dicates a tail piece extending from the portion 61 andprovided with an inwardly extending projection 67.

cated particularly by dotted lines in Fig. 3 of the drawings. q-Vhen thearm supporting member 60 is in position shown by dotted lines in Fig. 3the projection 67 bears against the lower face of the geared portion ofthe revolublemember 36. 68 68, indicate a series of arms, each armcomprising an inverted L-shaped portion, the short arm 68 of the Lextending inwardly and radially of the revoluble member 36 and restingupon the flange portion 64 of the member 60. The inner end of the shortarm 68 is provided with a hooked portion 69 which extends through theorifices of the lugs 59 and through the orifice 62 of the hub 61 formingthe pivot pin of the member 60.

7 0 indicates an L-shaped bolt extending over the arm 68 against thevertical flange 70 of the member 60, the vertical portion of the oltbeing provided with a threaded The tail piece 66- normally extends abovethe lugs 59 as indi end extendin throu h the orifice 6 1* bein D D :3

secured therein by a nut 71.

The lower end of each arm 68 is provided with a forked end 72. 73, 7 3,indicate the gathering forks. The upper end or-shank of each gatheringfork 73 is provided with a double cross arm 7 4, the outer end 7lofwhich is pivoted into the forked end of the arm 68. It will be noticedparticularly on referring to Fig. 10 of the drawings that the shank ofthe fork joins the arm 74 intermediately of its length, instead of atthe inner end. By this means when the fork receives the load it does notexert as great a leverage on the arm 68 tending to carry the arm outwardaway from sheaf tending to free the sheaf. By constructing the fork asdescribed the sheaf is held positively until it arrives at the trippingpoint to be discharged. 7 5 75, indicate levers. A lever 75 is pivotedintermediately of its length to each of the lug portions 65 by bolts 76.77 indicates a link connecting the inner end of each lever toeach of thearms 58 of the sleeve 58. 78 indicates a bar pivoted at its upper end tothe outer end of each lever 75 and provided at its lower end with anoutturned portion 79. 80 indicates a link bar secured at its upper endin the out-turned portion 79 and pivotally secured at its lower endbetween the inner ends of the double cross arm 74 of the gathering fork73. The cupped member 39, hereinbefore referred to, is provided with arecessed portion 81 formed in the lower face of the cup and providedwith a vertical wall 82 and an inclined wall 83. 84 indicates a trippingpin carried by the sleeve member 58 and extending at its upper endbetween the spokes of the revoluble member 36 and bearing against thelower face of the cup member 39. 85 indicates a lever swung upon theupper end of the axle 35 and fitting within the recess 38. The outer endof the lever 85 projects outwardly beyond the circumference of therevoluble member 36. 86 indicates a bracket inverted U-shape in form andsecured to the lower face of the lever 85 between the inner periphery ofthe gear portion 37 and the outer periphery of the annular flange 410 ofthe cup member 39. 87 indicates a spring plunger held in the bracket 86and provided with a headed end 88 held in engagement with the ratchetteeth 41 formed in the flange 40. 89 indicates a link rod which extendsfrom the outer end of the lever 85 to a suitable operating lever (notshown) located in proximity to the drivers seat. 90 indicates a springpressed locking dog pivotally carried by the radial extension 22 of theplate 21 in engagement with the ratchet teeth 11. By this means therotation of the cup member 39 in the direction of arrow (see Fig. 4) isprevented. A cord 91 extends from each 0f the bars 78 to the side of thecorrespond ing pocket of the receiver 43.

It will be noticed that the weight of the arms 68 and co-actingmechanism serve to hold the pin 84 in close contact with the lower faceof the cupped member 39. .92 indicates a cam piece carried by theextension 23* of the portion 23 in close proxlmity to the outerperiphery of the geared portion 37 and in the path of the upwardlyextending inclined portions of the tail pieces 66. 100 is a compressormember. The member 100 is attached at one end to the tubular bearing 16and'extends around "in the form of a semi-circle to the point 100 andbears against the horizontal portions of the arms 68 so asto hold themdown and the sheaves vertical. As the machine is traveling in thedirection of arrow (see Fig.1) it is essential that the sheaves at theback portion of the device drop vertically on to vthe ground otherwisesuch sheaves would be overthrown by the forward travel of the'machine.machine carries the heads of these rear sheaves forward inclining thesesheaves toward the center of the shock. The sheaves dropped at the frontportion of the device are not held by the compressor bar and,

therefore, the corresponding arms 68 tendto swing out and drop thesesheaves in an inclined position against the rear sheaves.

Having described the principal parts involved in my invention. I willbriefly describe the operation of the same.

Thesheaves are delivered and tied on the binder deck in the usual manneragainst the compressor arm 2. The delivery arms5 and 6 are carriedaround to deliver the sheaf. The cams 10 and 11 which, as hereinbeforedescribed, gradually increase in radius in the direction of travel ofthe delivery arms 5 and 6, serve to give a forward throw to the deliveryarms 5 and 6 as they travel radially around and therefore when they comeinto contact with the sheaf tend to throw the sheaf more quickly upwardThe cam 11 is slightly larger than the cam 10 and, therefore, the arm 6leaves the cam 10 before the arm 5 leaves the cam 11. The arm 5,therefore, gives the sheaf a greater throw than the arm 6 so as to carrythe sheaf into a vertical position. The shaft 27 is continuously drivenfrom the knotter shaft as long as the knotter shaft rotates by means ofthe gears 31 and 32, shaft 29 and pinions 33 and 28. By this means thepinion 34 and gear 37 of the revoluble member 36 is driven from theknotter shaft so as to rotate such member in the direction of arrow (seeFig. 1). By this means the tail pieces 66 are successively carried intoengagement with the cam piece 92. The cam piece 92 depresses the tailpiece 66 as'it is brought into contact "therewith so as to The forwardtravel of the" swing the arm 68 outwardly into the position shown at ain Fig. 1 of the drawings.

As above described the delivery arms 5 and 6 throw the sheaf upward intoa vertical position, the upper portion of the sheaf coming in contactwith the cord 91 when the cord is in the position shown at a. When thesheaf is thrown into this position the tail piece 66 is carried free ofthe cam piece 92- so that the arm 68 is freed. Simultaneously with thisoperation the sheaf strikes the cord 91 exertingan inward pull on thearm 68 assisting in drawing the fork ward and inward by gravity. thendrops to a vertical position carrying the sheaf into the correspondingpocket 19. Each pocket 19, 50, 51, 52, 53 and 5% receives its sheaf inthis manner. The vertical pin Sa is also carried around with therevoluble member, sleeve 58 and sheaf receiver 43 .(in the direction ofarrow see Fig. 1). When. all the pockets of the sheaf receiver have beenfilled the pin is brought opposite the recessed portion 81. By thismeans the forks 73 are freed so that the weight of the sheaves throwsthe forks downwardly toward a vertical position, the lever 75 beingtilted on its pivot and the sleeve 58 being. carried upwardly on theaxle 35 and the upper end ofthe pin 8 f carried into the recessedportion 81. l/Vhen the sheaves are freed as above described they dropdown- '73 into the sheaf as the arm 68 falls down- The arm 68 A sheafengaging position. This operation is repeated all around the field. Atthe end of the cut it may be that the number of sheaves gathered by theshocker is not sufficient to form a complete shock and therefore willnot automatically drop the sheaves before a new cut is started. In orderto accomplish this the driver of the binder operates the lever 85 so asto turn the cupped member 39 by means of the spring plunger 88 andratchet 4 1- in' the opposite direction of arrow indicated in Fig. 1thereby turning the cupped member back so that the recess is againbrought opposite the pin 84 by successive operations of the lever 85 soas to drop the number of sheaves held in the receiver. A new cut ofgrain may then be started so that the shocks formed and deposited willbe in alinement with the shock formed from the previous'cut.

From this description it will be seen that I have devised a very simpleconstruction of machine which will be light and durable and; which willnot only automatically gather the sheaves into a complete shockanddeposit the shock when complete upon the ground in a verticalposition but will also when the machine comes to the end of a cutdeposit any number of sheaves which may be gathered by the machine andwhich will not form a complete shock before a new cut in the grain isstarted and thus will insure the shocks being set up evenly in the fieldand therefore more easily gathered when required.

I am aware that cams have been used before for operating the deliveryarms for ejecting the sheaf from the binder deck. it has been found,however, that these cams do not throw the sheaf with suiiicientquickness to insure that the forks "Z3 engage therewith when the arm 68is freed from the cam 92. in order to overcome thisdefcct I have formedthe cams .vith a gradually increasing radius which gives a quicker throwto the delivery arm as it revolves-around to the delivery positionagainst the sheaf so as to carry the sheaf quickly into the path of thefork T3 simultanecusly with the freeing of the arm 68 and cemmencementof its fall inward toward the receiving pockets.
